Imagine looking at two brains that appear identical. They are the same size, have a similar number of brain cells, and possess comparable connections between different regions. Yet, one brain is smarter than the other. Why is that? The secret might lie in the way these connections are organized.
In the past, people believed that bigger brains were superior or that each brain part had a specific function. However, we now understand that brain functions rely heavily on communication patterns. This new understanding of brain activity shares some intriguing similarities with the game Twister.
To delve deeper into this concept, I consulted an expert in this innovative approach to understanding brain function. This perspective is known as networked neuroscience. Researchers use brain imaging techniques to map out the major connections between brain regions. These regions act as nodes in a network, with the connections between them resembling a network of train tracks.
The wiring of your brain network displays different patterns that constantly shift, especially when you learn or multitask. A new theory suggests that the way this wiring adapts to intellectual tasks is the best predictor of intelligence.
Danielle Bassett, an associate professor of bioengineering at the University of Pennsylvania and a MacArthur Fellow, is a leading figure in this field. I visited UPenn to meet with Danielle and learn more about this network approach. She studies how brain networks respond to various activities, such as learning something new. When someone learns, the pattern of connections in the brain changes, highlighting which parts are communicating with each other.
We are discovering that different brain regions communicate in novel ways. This is where the game Twister comes into play. The structure of Twister serves as a simplified analogy for understanding these brain networks. Different parts of your brain can be likened to players in the game, forming connections as they engage in activities.
As people learn, these connections can change, forming new patterns. This dynamic nature of brain connectivity is referred to as cognitive flexibility. It is the ability to switch from one task to another and can be an indicator of intelligence. The faster your brain can adjust its connectivity in response to changing tasks, the better it functions, enhancing your ability to learn new things, multitask, or switch between tasks.
Recent research suggests that general intelligence depends on this dynamic reconfiguration of brain networks. However, like most research on intelligence, it raises further questions. Cognitive flexibility is certainly associated with intelligence, but it does not fully explain what intelligence is.
Is there a way to enhance cognitive flexibility to become a faster learner or a better multitasker? Current findings indicate that individuals who are excellent learners have highly adaptable networks, with patterns of connectivity that change rapidly. This adaptability is influenced by factors such as mood, sleep quality, and nutrition.
Researchers suggest that exercise can also boost cognitive flexibility. While these recommendations may seem straightforward, they stem from complex analyses of the human brain. Neuroscience is revealing that it is not just about individual brain regions or connections; it is about the overall pattern of connectivity, which reflects a high level of complexity.
Reconfiguring patterns in your brain requires energy, and certain configurations can be challenging to achieve. Often, we revert to patterns that require the least energy. Breaking out of these patterns is often the first step in changing the way you think and can even enhance creativity.
Fortunately, this kind of neural flexibility does not correlate with physical flexibility. So, while you may not need to be a Twister champion, understanding and enhancing your brain’s connectivity can lead to greater cognitive flexibility and intelligence.
Engage in a hands-on workshop where you will use brain imaging data to map out the connections between different brain regions. This activity will help you understand the concept of networked neuroscience by visualizing how brain regions act as nodes in a network.
Participate in a Twister-inspired game designed to simulate brain connectivity. Each player represents a brain region, and the connections you form with others mimic neural pathways. This activity will illustrate how dynamic connections in the brain contribute to cognitive flexibility.
Attend a seminar featuring a guest lecture from a neuroscience expert, followed by a Q&A session. Prepare questions about cognitive flexibility and networked neuroscience to deepen your understanding of how these concepts relate to intelligence.
Challenge yourself with tasks that require rapid switching between different types of activities. This exercise will help you experience firsthand how cognitive flexibility works and why it is crucial for intelligence and learning.
Conduct research on methods to enhance cognitive flexibility, such as exercise, nutrition, and sleep. Present your findings to the class, discussing how these factors influence brain connectivity and intelligence.

Now, take a look at these two brains. They look identical, right? They are the same size, have roughly the same number of brain cells, and the same number of connections between regions. However, one is smarter than the other. So, why is that? The answer may lie in those connections.
We used to think that bigger brains were better or that each part of the brain had a single function. Now, we are learning that almost everything the brain does relies on a pattern of communication. This new perspective on brain function has some interesting similarities with the game Twister.
To explore this concept further, I sought out an expert in this new way of thinking about brain function. This big-picture perspective is called networked neuroscience. Researchers use brain imaging techniques to create maps of the major connections among brain regions. These regions become nodes in a network, with connections or edges between them, similar to stations in a network of train tracks.
The wiring of your brain network has different patterns that shift constantly, especially when you learn or multitask. A new theory suggests that how this wiring changes in response to intellectual tasks is the best predictor of intelligence.
